SILVA


A single tree and position dependent simulator and a flexible tool for predicting the impact of various forest management regimes on forest dynamics over one generation, accommodating treatments at stand-scale and larger scales, including landscape and country-level simulations.

Description of the model and use in OptFORESTS


The SILVA simulator is a simulation tool designed to predict the impact of various forest management regimes over the course of one generation. It accommodates a wide range of treatments, providing forest managers and researchers with valuable insights into how different management strategies may affect forest dynamics. Originally developed for stand-scale applications, SILVA's flexibility allows it to be extended to larger scales, including landscape- and country-level simulations.

In OptFORESTS, we use SILVA in research to explore and assess stand-level management strategies with a wide range of silvicultural techniques to evaluate the potential effect of genetic diversity on forest productivity and resilience, due to enrichment and the variety of resulting forest structures.


Main model information

SILVA 2.0 has a user-friendly interface in English. SILVA 3.0, with higher potential for large-scale applications, runs in C++.

It can be used for:

  • Single stand forest growth and yield predictions
  • Testing multiple management scenarios
  • Testing changes in forest structure due to species or genetic diversity

Norway spruce, Scots pine, silver fir, European beech, sessile and pedunculate oak, European larch and Douglas fir. Other species can be modelled as generic soft- and hardwood broadleaves.

Yes.

Yes.

Potentially all types of temperate forests.
